Full Job Description

About the role
As a QA Automation Engineer (Connex Payments) , you will make an impact by safeguarding the reliability, security, and performance of our payment systems, with a core focus on the Connex switch environment. You will be a valued member of the Quality Assurance/Enterprise Payments team and work collaboratively with engineering, payments operations, and compliance stakeholders to modernize QA practices across the organization.

In this role, you will:
Conduct end-to-end testing across core switch functionalities, including transaction routing, authorization, Stand-In Processing (STIP), Store & Forward (SAF), and switch interface validation
Analyze and test Switch Core & System Architecture (e.g., HP NonStop/Tandem environments, host interfaces, transaction engines) to ensure high throughput, resilience, and minimal latency
Parse and validate payment messages against ISO 8583, AS2805, and related network communication protocols across switch-to-host and switch-to-scheme interfaces
Verify End-of-Day (EOD) processing, batch file generation, clearing, interchange settlement, and reconciliation workflows between POS/ATM terminals, switches, and schemes
Design and execute API tests using Postman and build robust end-to-end automation using Playwright, integrating automated suites into CI/CD pipelines for fast feedback loops

Work model:
We believe hybrid work is the way forward as we strive to provide flexibility wherever possible. Based on this role's business requirements, this is a hybrid position requiring client or Cognizant office presence in Sydney, NSW. Regardless of your working arrangement, we are here to support a healthy work-life balance through our various wellbeing programs.
The working arrangements for this role are accurate as of the date of posting. This may change based on the project you're engaged in, as well as business and client requirements. Rest assured, we will always be clear about role expectations.
What you need to have to be considered
Substantial, hands-on experience with the Connex payment switch and a firm grasp of core switch functionalities (transaction routing, stand-in processing, message switching)
Well-developed understanding of switch core concepts, transaction flow engines, and Tandem/HP NonStop hardware and software platforms
Strong command of ISO 8583 and AS2805 message protocols, field definitions, and network layer communication
In-depth knowledge of settlement, clearing file generation, reconciliation processing, and EOD batch execution
Proven proficiency with Postman for API testing (environment setup, request chaining, mock servers, Newman collection execution) and Playwright for automated test suite development (JavaScript/TypeScript, Python, or Java)
These will help you stand out
Familiarity testing payment applications on Android-based payment terminals (e.g., Verifone Android terminals)
ISTQB certification or other payments industry certifications
Experience with automated payment simulators (e.g., Paysim/FinSim)
Working knowledge of terminal management interfaces (e.g., PAX, VHQ) or payment gateway integrations (e.g., Linkly)
Demonstrated use of AI tools (e.g., GitHub Copilot, ChatGPT, or custom AI test utilities) to accelerate test design and defect triage
We're excited to meet people who share our mission and can make an impact in a variety of ways. Don't hesitate to apply, even if you only meet the minimum requirements listed. Think about your transferable experiences and unique skills that make you stand out as someone who can bring new and exciting things to this role.
